MACHINE FOR COMPRESSING FILLING FOR IVIATTRESSES.

Specification of Letters Patent.

Patented Jan. 29, 1907.

Application filed January 26, 1906. Serial No. 298,042.

To all whom, it may concern:

Be it known that I, ABRAHAM A. SoHIM- MEL, a citizen of the UnitedStates, residing at Boston, in the county of Suffolk and State ofMassachusetts, have invented a new and useful Improvement in Machinesfor Compressing Filling for Mattresses, of which the following is aspecification.

' This invention relates to machines for compressing filling for use inmattresses, my present purpose being to provide a powerful, convenient,and simple form of press that may be operated by a single attendant andwhich may be quickly adjusted so as to compress the lilling to anydesired size within the limits of the said machine.

My said invention is illustrated in the accompanying drawings, Figure 1being a side elevation of a press embodying my improvements. Fig. 2 is aplan view of the same. Fig. 3 is an elevation of said machine from theleft-hand end of Fig. 1, and Fig. 4 is an elevation of the same asviewed from the righthand end of Fig. 1. Fig. 5 is an end elevation ofthe plunger 0 by means of which the filling is compressed; and Fig. 6 isa plan view of the same, illustrating also the manner of attachingthereto pressure-boards of different lengths in order to temporarilyincrease the width of said plunger. In Fig. 7 I have shown across-sectional view of the top pressure-boardand of the side boardsadjustably connected thereto; and in Fig. 8 I have shown in sideelevation portions ofthe top board, bottom board, and side board of thepressure-box, the side board in this instance being disconnected fromthe top board and supported by springs in such manner that when the topboard rises the side boards will be drawn upward by said springs. Fig.9. is a detached plan view of the top board of the form shown in Figs.1, 2, 3, l, and 7. 1

Referring to the drawings, it will be seen that my said press consists,essentially, of a box-like receptacle having a movable top and. sidesand having one end adapted to operate as a plunger within said box, thewhole being supported in and by a suitable frame. As here shown, saidframe consists of corner uprights a a, (at each side of the machine,)which uprights are connected by horizontal bars I) at the top of saiduprights. The said uprights are further connected and stiffened, at theends of the machine, by cross-bars c c 0 The ends of the bottom boardsof the press rest upon the cross-bars c and saidbottoin is made up of aplurality of narrow strips 01, preferably three inches wide, so that thepressbox may be reduced in width when it is desired to produce a narrowmattress by simply removing one or more of the strips d from each sideof the bottom-that is tosay, if it is de-v sired to produce a mattresssix inches less in width it is only necessary to remove a threeinchboard from each side of the bottom, thus narrowing up the bottom siXinches.

If it is desired to produce a mattress one foot narrower, two of thethree-inch boards should be removed from each side of the bottom.

The top pressure-board is indicated by the letter 6 and is arranged tomove vertically, the machine-uprights serving as guides for said top.

The top is held in its elevated or normalposition by counterweights f fthat are connected with said top by means of chains or cords f that runover score-pulleysf f as is perhaps best seen in Fig. 1 of the drawings.

During the operation of compressing the filling material within thedescribed press the top 6 is drawn downward by chains or cords 9, saidchains or cords being connected at one end to the corners of top 6 andat their other (lower) ends to shafts h h, which shafts are journaled inbearings secured to the machine-uprights.

Shafts h 72/ are connected by sprocket wheels and chains, as is bestseen in Fig. 3, and are thus caused to revolve in unison, shaft it beingthe driver. When these shafts are revolved in one direction, the cords gare wound thereupon, thus drawing the top board e forcibly downward, andwhen the said shafts are revolved in the opposite direction. thedescribed counterweights and cords f draw the said top upward as thecords g unwind from shafts h h.

The letters 7c 7c indicate side boards that are arranged to movedownward and upward with the described top board e. In the form ofmachine illustrated in Figs. 1, 2, 3, 4, and 7 the side boards aresecured to and are carried by the top board, the side boards beingprovided in their upper edges with bolts F, that lie in transverse slotse in the top board, (see Fig. 7,) and the sides and top are securelyclamped together when the machine is in use by means of nuts F, that arehere shown as hand-wheels.

It will now be understood that by partially tively, with bevel-gears nand If.

unscrewing the hand-wheels k and then adjusting the side boards towardor away from each other the width of the press-box may be materiallychanged.

In Fig. 8 I have shown the side boards supported by springs is, one endof each spring being attached to the side beard and the other (upper)end being secured to one of the machine-uprights by a bracket k Duringthe operation of the machine side boards are forced downward by the topboard e, which overhangs said sides, the springs 76 yielding meanwhileas the sides descend; but so soon as the top rises again the saidsprings lift the sides and cause them to follow the upward movement ofthe top.

The fixed end board of the press-box is indicated by thereference-letter m and may be removably secured in position by anysuitable means. As here shown, it is slipped down behind strong ironbrackets m, that are fastened to the machine cross-bar 0 (See Fig. 3.)This end board may be readily removed whenever it is desired to fill thepress-box or to remove the compressed filling.

The letter n denotes a screw-shaft that extends from end to end of themachine and hasmounted thereon a nut 0, which has an upwardly-extendingportion 0, that lies in a slot in the bottom board d, and secured to theupper end of the portion 0 is a transverse plate 0 that serves as theplunger of my press, the length of said plunger being equal to thenarrowest width to which the pressbox is to be adjusted and the height.of said plunger being equal to the least depth to which the said box istobe adjusted.

the

hen it becomes necessary or desirable to increase the width or depth ofsaid box, a board 0 of the proper length and height is placed in frontof the plunger and secured thereto, if desired, as indicated by dottedlines in Fig.6.

Having described that portion of my machine that serves as thecompression-box and the mechanism immediately connected there with, Iwill now describe the mechanism by means of which the shafts n and 7bare revolved and controlled. These shafts are extended somewhat beyondthe machine-uprights at one end and are provided, respec- The gear 7L2meshes with a bevel-gear p, loosely m ounted upon a shaft 2), located atone end of the machine and extending at right angles thereto. The gear ameshes with bevel-gears p 10 loosely mounted upon shaft 2) at oppositesides of said gear a, as is best seen in Figs. 2 and l of the drawings.Splined upon the shaft 17 are clutch-sections g g g that are adapted tocooperate with companion clutchsections formed within or upon the hubsof gears 19, p and 19 respectively, and said sphned clutch -sect1ons arecontrolled by forks s .9 s earned by a long1tudmallymov and 9 intooperative connection with their (ompanion sections, thus setting inrevolution the gears p and p and their connected shafts 71 and n.Simultaneously the sliding of rod if throws the clutch-section 9 out of(hitch with its companion sections, and thus allows the gear 1) to berevolved idly. The revolving screw-shaft n causes the nut 0 andconnected plunger to move forwardthat is to say, toward the end boardmand at the same time the revolving shafts 7t h and attached cords orchains 9 draw the top and side boards of the compression-box downward,thus forcibly compressing the contents of the box into the desired sizeand shape. The rod t is then moved so as to throw out theclutch-sections q q", thus allowing the shafts 7i n to stop,when thecounterweightsf immediately lift the top board to its highest position.rod 25 throws the section q into clutch with its companion section andsets the gear p in revolution, thus revolving gear a and shaft abackward and causing the nut 0 and plunger to travel back to theirinitial position. The end board m may then be removed and the compressedfilling drawn out from the compression-box and slipped into any suitableor desired form of cover or ticking.

Many of the non-essential details of my described machine may be changeduithout departing from the spirit and principle of my inventionas, forexample, the particular form of clutches employed is not material or themanner of supporting the end board m.
